WM490U Tektronix Mixer

The WM490U is a used 60 GHz Mixer from Tektronix. A waveguide mixer is electronic test equipment engineers use to achieve low conversion loss and flat frequency response. Engineers use external mixers, harmonic mixers, preselected mixers, millimeter mixers, and general-purpose waveguide mixers to ensure an electronic device exhibits a flat response (the same input and output).

The Tektronix WM490U waveguide mixer covers a range of 40 to 60 GHz and are compatible with the 2750, 2780, and 490 series spectrum analyzers. The 015-0385-00 diplexer assembly is required for utilizing external mixers with the aforementioned analyzers.
